Centrifugal Barrel Finishing

What is Centrifugal Barrel Finishing?

In its most basic form, this approach consists of a turret and four barrels which rotate at a high speed exceeding 300 RPM. At these speeds, G forces in excess of 30Gs can be generated inside the barrels. The centrifugal force pushes the work pieces and the media to the periphery of the barrels. Since the barrels are rotated in the opposite direction of the turret (similar to a Ferris wheel) at a 1:1 ratio, a slide is created within the barrel which causes the media to move across the work pieces and abrade the surface removing minute amounts of material at every rotation. Due to the high centrifugal force, the work pieces do not tumble, thus eliminating part-on-part impingement that other systems are prone to creating. By implementing extremely high gravitational forces upon the media mass, a high amount of aggression is exerted upon the part load, resulting in a drastically reduced cycle time in comparison to alternative methods of mass finishing. The system can completely automate the finishing process.
